My Coupe's MOT was today but when I got in the car the battery was flat as a pancake because I'd left the radio on for about 3 weeks. Made a later MOT appointment and called out the RAC. Patrolman said battery was knackered and should be replaced, that it would never recharge on just the alternator, that it was only charging at 2 volts. I was a bit suspicious as the battery isn't that old, so I refused the new battery at £130, and after he'd left I took the car for a blow up the motorway. Noticed volt meter was reading 12 volts as usual. Car has started first time all day and performed faultlessly on MOT test with all the stopping and starting.
So! Do RAC patrolmen get commission for selling batteries? And if so, are they routinely making people replace perfectly good batteries? And are they no longer on the side of the motorist, but just out to make maximum profits?
